These headphones fit perfectly in your ear and are very comfortable, unlike many others!!!! Also good for exercise due to their good hold on the ears. I had my last set for around 5 years before they gave up on me. I bought 3 other different brands after this including Samsung, Philips and Sennheiser. The Samsung ones didn't last the week, with the Philips I could't hear anything once I stepped out your front door and the Sennheiser's were so uncomfortable that they were painful to wear after 20 minutes os so at which point I would wear them outwith my ears and couldn't hear anything. I then bought another pair of Sony MDR-J 20 and once again I can enjoy my music. Going to buy several more pairs in case they cease production and I have to purchase every brand again and still be unhappy!!!!
I have read reviews that these are not good for exercising??? I must have abnormally big ears or I am doing the wrong exercise but I run about 100 miles a week with these and they have never failed me.
The only choice of headphones for me.......... Great sound quality, perfect fit and a great price. I paid 3 times more for other headphones which were no where near as good.
